Great sound and simple good looks for any room

Cambridge Audio's compact S20 bookshelf speakers are no strangers to sonic agility and power. Delivering a deliciously crisp treble and surprisingly deep bass, these monitors are ideal as part of a home theater setup, as a stereo music system, or as hi-fi desktop computer speakers in smaller rooms. With their good looks and versatility, the S20 speakers make a great budget speaker pair. Want even more bass? Just add a powered subwoofer and listen to these babies really come to life!

Designed and engineered with passion

All of Cambridge Audio's S-series speakers are carefully designed and tested at their London facility by a team of engineers fueled by a passion for incredible sound. Each S20 speaker uses a 1" soft dome tweeter for silky smooth highs. It features a state-of-the-art motor system with a neodymium magnet and critically selected voice coil assembly. The 4" woven composite woofer delivers accurate midrange and powerful, yet controlled bass with minimal distortion.

A rigid phase plug at the center of the woofer cone improves the S20's off-axis response, so you can enjoy seamless audio even if you're not sitting directly in front of your TV or sound system. And the custom-designed first order crossover sends the right frequencies to the right drivers to keep your music and movie soundtracks sounding faithful to the studio original.

The solidly braced MDF cabinets help prevent unwanted resonance from coloring the sound. Plus, the pair is video shielded for safe placement next to older tube TVs or computer monitors.

Why choose bookshelf speakers?

Bookshelf speakers may be small in size, but they can deliver surprisingly big sound. Some ultra-compact models even fit on a desktop. Most are right at home in tight spaces like shelves, so they're usually good choices for your home theater's rear channels. For the best performance, try placing bookshelf speakers on solid speaker stands to help the sound really "open up." If you want full bass impact, add a powered subwoofer and enjoy punchy sound that's as deeply satisfying as that of floor-standing speakers.

Cambridge Audio S20

Small speakers, very well constructed, great for small room. The finish is very good, I really like the name on the speaker cover is darkened adds a nice touch. Bass is weak, maybe if the speaker was ported, it would be better. Overall very balanced and smooth for the price.

Cons:Not real wood, but colored vinyl, however the dark-oak color is close enough to complement my oiled-walnut speakers. I would caution people not to hang on wall (unless with strong screw anchor) because the units are too weighty for a mere picture-hanging nail.

Magic in a box

Written By MW, Schenectady on Saturday, August 09, 2014

Sometimes things just work...whether it's the proximity of the drivers, cabinet dimensions, sealed cabinet or whatever, these little guys are the real deal. The sum is surely greater than the individual parts. If you prize clarity of midrange and spacial cues, these will not disappoint. A little tight out of the box, but let them break in...I run them with a Qinpu A3 8.5wpc hybrid tube amp and have never been more delighted. Add a sub to fill out the lowest bass notes if you desire (I use a paradigm sub-8, also a sealed design) but actually enjoy listening to them sans sub. Also work well for studio monitors and mixing music...truly sublime.

Cambridge Audio S20

Great sounding little speakers! Perfect for rear speakers in my home theater. The one complaint I have is that they are listed as book shelf speakers which they certainly look like, but they are technically stand speakers and therefor were not attachable to the speaker mounts I already had. I had to hang them directly to the wall which the instruction sheet did not recommend.

Cambridge Audio S20 Speakers

Very impressed with the Cambridge Audio bookshelf speakers! Superb sound which brings my old music of the 70`s & 80`s back to life. Would highly recommend these to anyone wanting a cost effective pair of speakers. They arrived as promised with great packing as well as fast delivery. Very good Advisors who are very knowlegable with their products!

Cambridge Audio S20 Speakers

These little speakers sound terrific. I'm using them primarily for Pandora thru my Roku. To up the bass I connected a Bose sub and the sound is more than adequate for our family room; although they require the amp be bumped up slightly. The speakers deliver a rich sound, especially when you consider their small size.

Pros:Excellent size for our built in cabinets. My wife cannot stand large stereo speakers that distract from here shelving arrangements.

Nice little speaker!

Great sound for the size and cost of the speakers. Nice and neutral. Highs and midrange are crisp. Bass is a little soft, but what do you want from such a small enclosure. Fit and finish are nice for the price.

Excellent Little Speakers!

These are very nice looking, excellent sounding little speakers. I have them in dark oak and the veneer is good quality with a nice satin finish. I'm using them for my work/office setup as computer speakers powered by a Topping TP20-MK2 class T amp and they perform perfect for me. The frequency response is what the specs state (I measured 80hz - 20khz @ +/- 3 db with a bit of a hump at 111hz) so you'll want to use a sub to get any useable bass below 100hz. Other than that, the imaging and clarity is very good given the price. They sound just as nice as the Axiom M22s I run in my home theater setup. Off-axis response is also quite good.

Great little speakers

Great little speakers! I was looking for a set of small-ish speakers for my home office to go with the Cambridge AR30 receiver I bought a few months ago. I have limited flat spaces, so I bought a pair of Sanus BF13 stands to go with them. The sound great. There's an appealing brightness to the sound. The bass is more than adequate for a small room but you can always add a subwoofer to give you a bigger punch. Overall, I'm very pleased and would recommended them.

retro gamer

Amiga demo scene music has never sounded better! Great little speakers for the price. I have terrestial radio, pc, and hand-held gaming device audio comming through these speakers (via a nad326) and for those sources, these speakers are a great buy.

Nice little speakers

Out of the book, they were a little stiff and peaky in the midrange, so I've been playing bass-heavy EQ'ed music through them to loosen up the speaker cones, and they've opened up nicely. They have plenty of bass response for music playback without a sub in my 10'X10' bedroom. Overall, they're really, really nice for 4 inch bookshelves at a great price.

Good Value Speakers

I bought these to replace 25-year old KEF Series C speakers that took on a distortion in the right speaker. My amplifier is 25-years old with 35-watts per channel, if I recall correctly.

The mid- and high-end on these new speakers is very good. I put in a Police CD and listened to "Roxanne" (lots of high-hat and guitar chords) and "King of Pain" (wonderful bass line). As mentioned, mid- and high-end is excellent. Bass is very good for speakers this size, though not quite as good as my old KEF. But plenty adequate for my needs. And the price/value ratio is very good. No complaints.

Pros:Small, compact, good mid- and high-end.

Cons:Adequate but not great bass, as is to be expected with speakers this size.

For their size.....they do alright.

For the size of these speakers, they put out a nice, clear, full, balanced sound. They have more bass than I expected. I'm using them as my B speakers with my Onkyo S9050, so I don't have to blast my A channel, JBL floorstanding speakers, when I just want to watch some TV. With the S20's, the TV audio is plenty loud and clear.

These will work well for listening to music too. Albeit, for a smaller room. For critical listening however, they won't fill the living room with a huge wall of sound, that's what the big floor standing JBL's are for.

The Little Beasts

Written by Mike, Technical Support Advisor 4,

Recently, I wanted to update my computer speakers. I've tried a few different cheapo 2.1 speaker systems over the past few years; I was ready to spend a little more and get a small, simple system with better dynamic range and frequency response.

The Cambridge S20 speakers are developing an underground reputation as "The Little Beast." They are fairly small bookshelf speakers, only 5 inches wide, 8 inches tall, and 8 inches deep. Despite their small stature, these speakers have impressive bass response. But their primary strength is the clarity and definition in the midrange and high frequencies. Thanks to these "Little Beasts," I can hear details in my music collection I never knew existed.

The only complication from upgrading my speakers if that I now have to re-import my CDs in FLAC format. Due to the increased detail in these S20s, I can really hear the improvement in lossless audio formats. It reminds me of when I bought a high definition television  only then did I appreciate high-resolution video content.I guess I have something to keep me busy this winter.
